srEcIFIcATIoN forming part o'f Lefeersraeene No. 685,266, dated october 29, 190i.

Application filed September 8 1900. Serial No. 29,394. (,No model.)

Tb all whom, t worry concern:

Be it known that I, JOHN FLESHER, asu bject of the Queen of Great Britain, and a resident of Parry Sound, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Grain-Door, of which the following is a full, clear, and exact description.

The invention relates to a special form of door for grain-cars or other receptacles or 'conveyances employed to receive and `transport grain or similar substances.

The purpose of the invention is to construct the door in sections, one section being especially adapted for use when the grain is to be loaded in to a car or ventilated while in the car, another section being particularlybrought into action when the grain is to be unloaded, While the other or central connecting-section is arranged to receive the upper and lower sections of the door and to swing upward to the roof of the car, thus uncovering Vthe entire doorway.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures. y

Figure 1 is an outer face view of the improved car-door and the door-jamb. Fig. 2 is an inner face view of the improved cardoor and jamb. Fig. 3 is a transverse section through the car-door and adjacent portions of the car-body, the section being on a larger scale than shown in Figs. 1 and 2 and the door being shown closed. Fig. 4 is a view similar to Fig. 3, the lower section of the door being shown open for the purpose of discharg-` ing grain andthe upper section of the door open for the purpose of ventilation. Fig. 5 is a view similar to Figs. 3 and 4, the upper and lower sections of the door being folded upon the main or intermediate section. Fig. 6 is a section through the door-jamb and a portion of thereof of the car and a section through the door, with the parts folded together and the entire door heldl horizontally close to the roof of the car; and Fig. 7 is a horizontal section taken through the lower section of the door.

A represents the dcor-jamb; B, the bottom vportion of the car; B', a portionot the roof of the car; C, the upper section of the car-door; C', the intermediate or main section of `the door, and D the lower section,which is brought into action when grain is to be'discharged from the car.

A guide-strip 10 is secured vertically upon the inner faces of the door-jambe, as is shown in Fig. 2, and the lower portion of each guidestrip 10 is provided with an enlargement 12, whereby an upper shoulder 11 is formed, and a recess 13 is made in the upper end of each enlargement or extension 12 at its inner vertical edge, as is also shown in Fig. 2. These recesses 13 are-adapted to receiveextensions 14 from the upper end portions of the lower section D of the door, and these extensions or lugs 14 constitute swing-bearings for the said door, enabling the door to open outward, as shown in Fig. 4, so that'the grain or material in the car may iind exit therefrom. When the grain-door is closed in its entirety, the lower section D is vertical and is prevented from being carried too far inward by engagement with stops 15, secured to the iioor of the car, as is best shown in Fig. 2.

When the door is closed, the intermediate section C of said door rests upon the shoulders 1l of the extensions 12 of the side guides 10 and upon the upper edges of the lugs 14 of the lower section D of the door and extends from one guidelstrip to the other; but the intermediate section C of the door is capable of being moved bodily out from between the guide-strips 10 when the lower section D of the door is inclined or partially open, as shown in Fig. 4. This intermediate or main section C of the door is strengthened bybattens 16, located upon its inner face, and is providedwith a handle 17, also upon its'inner face, the handle extending horizontally or at an angle to the said section, Furthermore, the intermediate section C of the dooris provided with an angular button 18, and Vthis button serves to hold the upper section C of the door close to the inner face of the intermediate section of the door when the upper section of the doorlis folded down upon the intermediate section, as shown in Figs. 4and 5, since `the upper section C of the door is connected with the intermediate section C' by hinges 19 of any suitable description.

The upper section C of the door is of less transverse dimensions than theintermediate section C', as shown in Fig. 2, and when the Upper section C of the door is closed, as shown in Figs. 2 and 3, it may be held closed by a button 20 or its equivalent pivoted to the outer face of the said uppersection, which button enters a groove or opening 20 in the upper sill of the door-opening, as shown in Figs. 3, 4, and 5. When thelowersectionD of the door is closed, battens 21, secured vertically upon its inner face, extend up beyond 4the upper edge of the said lower section to an engagement with the intermediate section C', so that when the lower section D is locked the intermediate section C is locked also.

The intermediate section C of the door has a hinge connection with the upper portion of the door-jamb. This hinge connection consists, preferably, of bars 22, pivoted at their upper ends to brackets 23, secured to the inner face of that portion of the car near the roof surrounding the door-opening, and the lower' portions 25 of the rods or bars 22 are loosely passed through eyes 24, secured to the inner face of the intermediate section C of the door, at or near the upper corners thereof, as is best shown in Fig. 2, and each rod 22 near its upper or pivoted end is provided with a hook extension 26.

It may here be remarked that when the upper section C of the door is folded down and secured to the central or intermediate section C' the lower section D may be removed from the door and made to rest at its bottom upon the handle 17, while the extended portions of the battens 21 will enter the space between the upper and intermediate sections, as is particularly shown in Fig. 6. At such time the intermediate section C of the door is pushed upward until the eyes 24 engage with the hooks 26 of the hinge-rods 22, whereupon the door in its folded or compact condition is carried up to the horizontal position shown in Fig. 6, and the handle 17 -is made to engage with a suitable keeper 27, which extends from the roof-section of the car. When the intermediate and lower sections of the door are locked, the upper section C may be left open, so that the car may be filled with material or so as to ventilate the contents of the car when ventilation is needed. At such time the intermediate section C is prevented from being pushed upward away from the lower section D of the door by means of hooks 28, pivoted to thc door-jambs, which hooks extend-over the upper edge of the intermediate section C' and engage with the inner face of said sect-ion. It will be understood that these hooks 2S are disengaged from the intermediate section C' when said section is to be elevated, and such disengagement can take place only when the upper section C of the door is opened.

A plate 29 is secured to the inner face of each door-jamb at the bottom portions thereof, and inclosed spaces 30 are thereby formed between the said plates and the jambs, as shown in Figs. 4 and 5. These spaces 30 are adapted to receive locking devices carried by the lower section D of the door at the outer face of the same. The lower section D of the door is provided with a sleeve 31 at its center, and this sleeve has a flange 32, which engages with the outer face of the said section D, as is particularly shown in Figs. 3 and 4. The sleeve 31 loosely receives a spindle 33, and this spindle is passed through a washer 34 at the inner face of the door, and said spindle is held in position by a pin 35 or the like. The spindle 33 at the outer face of the door-section D is provided with a disk 36 and an enlargement 37 at the inner face of the disk, which has bearing upon the sleeve 31. The outer or front end of the spindle 33 is provided with a polygonal section 38, adapted to receive a Wrench, key, or the like.

The locking devices heretofore referred to as entering the spaces 30 between the plates 29 and the jambs, or, lnore properly, the extensions 12 from the guides on said jambs, consist of plates 39, which are vertically located one near each end of the said lower section D of the door, having movement on wear-- plates 40, secured upon the outer face of said section, as is shown in Fig. 1. These lockingplates 39 are provided with transverse slots 41, through which pins 42 are passed, and each locking-plage 39 is provided with a re'- cess 43 in its inner vertical edge. These re'- cesses are adapted to receive the free ends of buttons 44, pivoted on the outer face of the said lower section D of the door, as is also shown in Fig. 1, and these buttons 44 when within the recesses 43 hold the outer edges of the locking-plates in the aforesaid openings 30. When the buttons 44 are disengaged from the locking-plates 39, these plates are simultaneously moved inward or outward through the medium of the following-described devices: A Y-rod 45 is employed in connection with each locking-plate, the bif urcated members of which rods are pivotally connected with the locking-plates near theirl top and bottom edges, and the Shanks of the Y-rods are provided with o'utwardly-bent sections 46. These bent sections enter openings in the disk 36, carried by the spindle 33, the Y-rods connecting with the said disk at diametrically opposite points. A bolt 47 is also provided, having an outwardly extending member 48, which likewise enters an opening in said disk 36, and this bolt extends upward through a suitable guide 49 and in one position is arranged to extend across the line dividin g the intermediate section C' of the door from the lower section D. Thus it will be IIO esaee observed that by turning the spindle 33 the locking-plates are simultaneously moved to or from their keepers, and the bolt 47 is moved at the same time to or from the intermediate section C of the door.

Having thus described my invention, I claim as new and desire to secure vby Letters Patent- 1.
